An official for Facebook told TechCrunch that the company is “continuing to cooperate with the relevant U.S. powers, ” as investigations into the Russian hacker of last year’s general elections continue to expand. In the recent developments, sovereignties are now investigating how agents used online marketing on social networks and pursuing pulpits, and tech companies are being forced to hand over new, sensitive information to investigators as a result.

In some examples, that necessitates affording different information to different investigations, as The Wall Street Journal is reporting today.

Facebook has apparently shifted over more detailed information to the special lawyer, Robert Mueller, than the company shared with Congress last week, the Journal reports.

Mueller’s investigation has received copies of the Russian-bought ads and detailed information on the specific account information materials and targeting criteria the buyers used to distribute their ads, in agreement with the Journal, citing people familiar with the matter.

It’s likely that Facebook was compelled to turn over the information because the analyse unit receives an search warrant.

If certainly, Mueller is using warrants, then it’s likely that Facebook won’t be the only tech company that may be forced to reveal information about potential clandestine ad buys, which Russian agents are alleged to have become in order to influence the U.S. election.

The Journal reports that Mueller’s team could have gotten information that Facebook withheld from Congress because of concerns around privacy statutes or horrors of interrupting the Mueller probe. My guess is that Facebook is likely also thinking that the Mueller investigation is a tighter ship and less likely to hole details of the ads whereas Congressional staffers could leak like sieves.

It’s clear that Facebook has no those who are interested in disclosing details of the ad buy, or telling men whether they were targets of what amounts to a Russian story to influence the U.S. election.

It’s something members of the tech community have taken Facebook to task for already.
